AWS Platform engineer

Braid is a fintech company building modern banking and payment infrastructure to empower Community banks and Credit Unions to compete and thrive. We are a lean, senior team that values ownership, collaboration, and moving fast without breaking things that moves billions of dollars.

The Role We are hiring a Senior AWS Platform Engineer to take ownership of our AWS environments. You will be the directly responsible individual for how our infrastructure is built, deployed, monitored, and secured.

You will work closely with the engineering team and founders. This is a hands‑on individual‑contributor role. You will spend most of your time writing infrastructure as code, improving our deployment workflow, tightening our security posture, and making production boring in the best possible way.

What You Will Do

Own the design, deployment, and ongoing health of our multi‑account AWS environment

Evolve our account strategy — improve environment isolation, security boundaries, and access patterns across accounts

Write and maintain infrastructure as code, and continuously improve how changes are reviewed, tested, and rolled out

Own VPC design, network segmentation, and security group hygiene across the platform

Operate containerized services and managed databases in production, including backups, upgrades, and capacity planning

Tighten the platform's security posture — IAM, network boundaries, secrets management, and compliance controls

Build and maintain monitoring, alerting, and on‑call runbooks so incidents are caught early and resolved quickly

Own cloud cost visibility — implement tagging, budgets, and reporting so the team understands what we spend and why

Partner with application engineers to improve developer experience and shorten the path from commit to production

Contribute to disaster recovery planning, incident response, and post‑incident reviews

Write clear technical documentation that your teammates and future hires can actually use

Required Qualifications

Five or more years building and operating production AWS environments — this is an AWS‑only shop and we need someone who already knows the platform deeply

Hands‑on experience with AWS infrastructure as code (CloudFormation, CDK, or Terraform with the AWS provider)

Strong networking fundamentals in AWS — VPC design, subnets, security groups, NACLs, Route 53, and routing

Production experience running containerized workloads on ECS or EKS

Solid operational experience with Amazon RDS, including backups, upgrades, parameter groups, and performance tuning

Strong working knowledge of AWS IAM and the ability to reason about least‑privilege access, SCPs, and permission boundaries

Experience owning the full incident lifecycle: detection, triage, mitigation, and blameless post‑mortems

Comfortable writing Python, Go, TypeScript, or Bash well enough to build and debug glue code and automation

Proficiency with AI‑assisted development tools — you use LLMs and coding assistants to move faster and expect to keep up as the tooling evolves

Excellent written communication; you write runbooks and design docs without being asked

Preferred Qualifications

Prior experience in fintech, banking, payments, or another regulated industry

Familiarity with SOC 2, PCI‑DSS, or similar compliance frameworks

Experience with AWS Organizations, SCPs, or multi‑account governance patterns

Experience leading an infrastructure modernization or migration without a big‑bang rewrite

Working knowledge of AWS security services and logging / audit tooling

Experience with AWS cost management, tagging strategies, or FinOps practices

AWS certifications (Solutions Architect Professional, DevOps Engineer Professional, or Security Specialty)

How You Work

You're biased toward making production safer, not toward chasing novelty

You write things down and treat documentation as part of the deliverable

You push back constructively when a request would take the platform in a worse direction

You are comfortable holding context for a complex system and moving it forward a step at a time
